PingPing#
Use PingPing to measure a PingPing
message passing between two
ranks in each pair of ranks.
Property |
Description |
---|---|
Measured pattern |
The ranks are broken into pairs: (0, N/2), (1, N/2 + 1), (2, N/2 + 2) and so on. The number of ranks N must be even. |
MPI routines |
|
MPI data type |
|
The benchmark reports latency (in microseconds), bandwidth (in million bytes per second), and message rate (in messages per second).
Note
IMB-P2P PingPing
and IMB-MPI1 PingPing
are different
benchmarks (IMB-MPI1 PingPing
uses MPI_Isend
, MPI_Recv
,
and MPI_Wait
).
